, BACKGROUND OF THE IMVENTION
- :
There are various methods and techniques employed for
! applying data cards or other forms of indicia to drums and
!I containers For example, a label may be attached to a part of
~I the drum and may be placed either on the drum itself or on
¦ its cover. If such information is placed on the cover, however,
and the cover is removed or exchanged, tbe pert1nent data and
information could be then completely lost or even be incorrect.
¦ If labels are glued to the drums, the~r;removal would~be;
!~ very difficult. Such removal lS oten nece~ssary as the containe
¦! ~oes down through production, and a series of inspectors desire
to afflx the approprlate~labels. If the~drum 18 later to¦¦be~
l used for a different purpose,~it will also be necessary to~
! attach the correct identlflcation lsbel.
SUMMARY OF THE I~VE~TIO~
,
~ It is ~an ob~ect of the invention~to provide an effectivs~
snd improved means for permittlng the securement of an identific
l tion tsg to~s drum which wlll allow its simple removal and in-
j~ staliation of another tag bearing dlfferent data.
;20 ~~It is ano her ob~ect of the invention to secure such tags
~to the drum~ltself snd wlthout the use of~an adheslve, so as
to avoid posslble confusion when the covers of the drums;ars
`~ rtmovsd~or sxchanged. ~ ;~

I~ Still another object of khis invention is to provide a
jj simple method of incorporating a means for attaching tags,
data cards or other identification to a drum without any sub-
I stantial changes in the manufacturing process of such drums,
ll thereby necessitating a minimum of added expense and labor.
In general, the invention provides~an improved drum or
container in which the means for afflxing identification labels
is incorporated within the structure of the drum itself. The
shell defining the walls or body o~ the drum is first con-
I structed, and a wire loop of sultable length is cut. The wire
¦¦ is placed over the top or upper rim of the~shell~so that it pro-
¦¦ jects downwardly on the exterior, and downwardly a short ;
I distance on the interior of the shell.~ A chime strip~oE suit- ;
¦ able material is then forced over the top edge of the shell,
and over the wire loop which is malntained in the proper
configuration by having been looped over the upper rim. When
the shell is ready for the beadlng operation, it is plaoed in
a shell beader to be formed into the desired shape. The
wire loop is formed rlght along with the bead, and projects
from the lower outer edge of the top chime strip. In this
manner the wire loop is secured by frictional engagement bet-
¦¦ ween tbe sl 11 and the cbime stFip

wire 10 as shown in ~ ure 1 alld reEerred to by the numeral 16-
The wire ls attached by means of frlctional enyagement by belng
em~edded between t~le drum shell 12 and the top chime strip 13
following completion of -the top chime construction. The free
end of the wlre loop 10 projects outwardly from beneath the
chlme strlp 13. The wire loop and tag or label may, of course
be affixed to either the top or bottom of the drum.
It should be understood that a number of materials
would be suitable for the manufacture of the drum, chime, and
wire loop. The drum body may be formed of wound laminated layer
of adhesively secured fibrous material on a shell winding
machine and then cut to the desired length. The wire loop :
may be composed of any suitable metal, although a non-metallic
cord could also be employed. The chime may be metallic and pre~
, :-. :.: .
ferably steel, as both strength and ductility are desirable
parameters to facilitate the manufacture of the drum of this
invention. ~ -
For the convenience of lllustration, only the upper
portlon of the drum body ls shown. The drum has side walls,
an upper end, and a closed bottom end.
In Figures 4 ~o 6 the process of manufacturlng the ~ ~ ;
completed drumof thls invention is shown and as will be
apparent to those skilled in the art, the method of constructing
a fiber drum having top and bottom chime strips need not be
radically altered. After the shell 12 of the drum has been ;~
cut to its desired length, the wire loop 10 of Figure 3 is placed
over

the top or upper rim of the shell so that it projects down- ¦
wardly on both the interior and exterior walls as depicted in ¦
Figure 4. The larger looped portion of the ~ire loop 10 is
!l located on the exterior free end so that it may be used to
~ affix the appropriate tag, label or data card. The metallic
¦ chime is then placed over the top of the shell as shown in
l Figure 4 with the wire loop now located between these parts.
¦ When the shell is ready for the beading operation, it is placed
ina shell beader and formed into~the desired shaped bead 14.
.
Figure S shows this shape to be a groove~on the outside of~the
drum with the corresponding rib shaped protrusion on the in-
side of the shell. The wire loop 10 assumes the shape of the
bead, and projects below the outer bottom edge of the chime
stop 13 (see Pigures 1 and~2) and the major part of the ~inner
loop end lS is dLsposed between the chime strip and inner
surfaces o the shells. The top chime construction is then~
completed by placing the beaded shell inla hydraulic press
9 forming die which curIs the top edge of the chlme over securely
~ and shapes the bead 14 to give it its final dimensions. (see
~ . ~ :
Figure 2) This final step assures that the inner end lS of~
! ~ ~ ; the~wire loop 10 is tightly embedded between~the chime strip
i ~ . :: ~ . ~
9' 13 and sheil 12 so that slippage and/or loss of the loop~-
~ will not ocour.
